' CHARLES F. COLLOM, OF NEV ORLEANS, LOUISIANA, ASSIGNOR TO THE NATIONAL WHARF AND BRIDGE COMPANY, OF NEW ORLEANS, LOUISIANA.

CONCRETE WI'IARF-SUPPORT.

Specification of Letters Patent.

Patented Nov. 14;, 1916.

Application filed January 20, 1916. SeralNo. 73,199.

To all 'uv/wm t may concern Be it known that I, CHARLES F. CoLLoM, a citizen of the United States, residing at New Gi'leaiis, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Concrete Wharf-- Supports, of which the following is a speelp ication.

vision of a simple, easily-produced and strong support for wharves, bridges and other structures.

Other advantageous characteristics of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure l is a view, partly in elevation and partly in section, showing my improved support. Fig. 2 is a detail section showing the base portion of one of the concrete columns mounted on a pile. F 3 is a detail horizontal section taken' through the head of one of the columns in the plane indicated by the line 3-3 of Fig. 1. Fig. 4L is a similar view taken through the base 'portion of a column in the plane indicated by the line of Fig. l. Fig. l5 is a detail section taken on the line 5-5 of Fig. l and showing the connection of tie beams to one column. Fig. 6 is an enlarged detail perspective showing one end of one of the concrete sway braces, comprised in the support.

Similar numerals and letters of reference designate corresponding parts in all of the views of the drawings.

My invention contemplates the employment on each of the piles P, which may be of wood or concrete, of a pre-cast column 1 of concrete or other plastic material, reinforced by a circular or other suitable series of vertical rods as clearly appears in Figs. 2, 3.and 5. The columns l are identical in construction, and therefore a detailed de? scription of the middle column shown in Fig l, and also .Shown in. Fiss 2 to 5 will suffice to impart a definite understanding of all. The column referred to is provided at its upper end with an integral head 8, and formed in said head and extending throughout the height thereof are recesses 9, of

"dovetail form in horizontal section. At its lower end the column 1s provided with an AI would have it understood at this point that it is not necessary to make the seats 5 Of dove-tail form, and therefore when de sired the said seats 5 may be made of even width throughout without affecting my invention.

The seats 5 in the base flange of the column specifically described are designed to receive tie beams 6, after the manner shown in Fig. 5; the said tie beams being designed to be interposed between the portions 4 of the several columns with a view to bracing and lending increased strength to 'the supporting structure as a whole. Manifestly the beams.` 6 may be of wood, concrete or other material, and they are held securely in position byV virtue of their interposition between the several columns.

Interposed between each pair of columns l are sway braces 10, of concrete or other suitable plastic material; each of said braces being preferably cruciform-c'- c., made up of crossed members. The said sway braces may bepre-cast, and then positioned between and keyed to the columns without departure from the scope of my invention. I prefer, however, to cast the sway braces between the columns, since this can be readily accomplished by arranging appropriate molds between the columns, pouring the plastic material in said molds, and then removing the molds subsequently to the setting or hardening of the plastic material. It will be noted in this connection that at their ends the sway braces 10 are provided with key portions, of dove-tail form in horizontal section; the upper key portions 4fully occupying the recesses 9 in the column heads 8, and the lower key portions fully eeeupyng the reeeeeee 7V. in the eelumn bases 2. ily virtue Aof this provision, the sway braces are strongly connected to the columns without the employment of eX-k materiel advantagefwhen it Vstated that bolts wil l af te r thelapse of ltime be destroyed Aby corrosion, and this .particularly true where the bolts ,are sillonierged.r
